CORN-SHELLER.

SPECIFICATION forming part of Letters Patent o. 396,375, dated January 15, 1889.

Application tiled May 3, 1888. Serial No. 272,703. (No model.)

To all whom it may concern:

Be it known that I, DAVID SNELLING, a citizen of the United States, residingin Adams township, in the county-of La Salle and State 5 of Illinois, have invented a certain new and useful Improvement in Corn-Shellers, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l is a central longitudinal section of a corn-Sheller embodying my invention; Fig. 2, a central longitudinal sectional view of the shelling devices enlarged; Fig. 3, a transverse sect-ional view taken on the line 1 1 of Fig. 2, and Fig. -l a similar view showing a modificat-ion.

Like letters refer tolike parts in all the figures of the drawings.

My invention relates to corn-shellers, and more particularly to the shelling mechanism thereof, wherebyithe grains of corn are removed from the cob, and has for its object to provide a construction whereby the operation of this mechanism may be rendered more certain and efficient.l

To these ends my invention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the drawings, A represents the body-casing of a corn-sheller of any suitable construction, and B a cylinder mounted therein upon a suitable shaft, B', driven from any suitable source of power. The cylinder B is preferably hollow and constructed of metal, and is provided with shelling-teeth l), arranged in several rows spirally around the said cylinder. Upon the exterior of the cylinder B there are arranged a series of wings, C, having a height substantially equal tothe height of the teeth l). These wings are of any suitable length and extend along the surface of the cylinder in a spiral direction, which pret'- erably corresponds to the spiral direction of the rows of teeth l). In the present instance I have shown these wings as arranged in two annular series around the cylinder B, one series of two wings beinglocated atthat end of the cylinder where the shelled cobs are discharged and the other series of two wings being arranged at about the middle ot the cylinder. Of course any desired number and arrangement of these wings maybe employed. The cylinder B is surrounded by a suitable casing, which, acting in conjunction with the 55 toothed cylinder B, serves to remove the grain from the ears of corn. In l, 2, and 3 I have shown this casing as composed of a cylindrical upper portion, D, of ordinary construction,\vl1ile the lower portion is composed 6o of square or angularbars E, extending lengthwise parallel to the cylinder and mounted in suitable supports, F. The bars E are placed a suitable distance apart, forming intermediate spaces, c, through which the shelled corn may 65 pass downward, while the cobs are prevented from passing through said spaces. The supports F are semicircular in form, and in the present instance I have shown four of these supports, although any suitable number may 7o be employed, according to the length of the cylinder and of the bars E, each ol' the supports being arranged just in front of a series of the spiral wings C. The bars are connected thereto by passing through correspondingly- 75 shaped holes in the supports, which are thus caused to project slightly inward above the said bars, as shown in Fig. 3.

Instead of forming only a portion of the casing of longitudinal bars, the whole casing 8o may be thus constructed, as shown in Fig. 4f, in which case the supports F will. be circular in form, and the entire cylinder B will be surrounded by a cylindrical casing composed of square or angular bars E, mounted in said 8 5 supports. In either case the supports F serve for the attaclnnent of acasing, G, which prevents the shelled corn from escaping, said casing being open at the bottom Ato permit the shelled corn to drop through.

H indicates au inclined spout, by means of which the ears of corn are fed to the shelling mechanism. In this spout is arranged a valve, II', hinged at. the top of the spout and swinging freely within the same. 9 5

The operation of the apparatus is as follows:

The corn which is discharged into the feeding-spout II passes freely by the valve H', which swings toward the top of the spout and permits the ears of corn to pass freely downroo Ward. At the same time, however, in ease any of the ears of eorn are thrown back by the aetion ot' the shelling-cylinder, the valve ll Will prevent their iiying out of the mouth ot' the spout II, which result it accomplishes in an obvious manner. The shelling-ease, Composed of the angular bars E, operates in conjunction with the teeth Z) of the Cylinder B to shell the eorn from the eob, and formsa Cheap and at the same time highly-efficient means for accomplishing this result. The spiral position of the teeth tends to feed the ears lengtlm'ise along tle shelling-Cylinder and its ease while being shelled, and this feeding motion .is `rendered more positive and expeditious by means of the spiral Win C. These wings also serve to force the eobs over the inwardly-projeeting supports- F and prevent clogging at these points. The Wings (l at the end of the Cylinder serve to positively feed the eobs out and diseharge them at outlet provided for. that purpose.

It is obvious that various modilieations in the details ot' eoirstruetion and arrangement of pa-rts maybe madewithout d eparti ng from the principle ot' my invention, and l therefore de not wish to be understood as limiting mysell strictly to the precise details hereinbefore described, and shown in the drawings,

Having thus described my invention, what I claim as n ew, and desire to seeure by vLetters Patent, is-

l. In a eorn-sheller, a shelling-Cylinder provided with teeth arranged spirally on the Cylinder and short spiral wings arranged at intervals in the spiral rows et teeth, in combination with a tubular Casin g surrounding said eliflinder, substantiall)7 as and tor the purposes specified.

2. In a eorn-sheller, the easing D, eomposed ot bars E and circular supports F, in eombination with the shelling-eyln der B, provided with teeth Z), arranged in spiral rows, and short spiral wings (l, mounted on said cylinder adjacent to the eireular supports F of the easing, substantiall'yT as. and :t'or the purposes speci ti ed.
